LOCK.

Application led September 24, 1923. Serial No. 664,569.

To all whom it 'may concern.'

Be it known that l, WILLIAM B. FAUL1-1- NER, a citizen ot the United States, residing at Paris, inthe county of Bourbon and State of Kentucky, have invented certain new and useful Improvements in Locks, ot which the following is a specification.

rlhis invention relates `to locks, and more particularly to permutation locks.

An object ot the invention is to provide a lock controlledby a pawl and a plurality of disks having notches, which notches must be arranged in alinement with each otherto permit the pawl to be actuated to release the hasp of the lock;

A Yfurther object is to provide a padlock ot this character in `which the combination may be changed innumerably by rearranging the disks. i i i A further object of the invention is to provide a lock ot this character which will be rendered inoperative if Vthe pawl is maintained in engagement with the `disks while the disks are being set, thus {.neventing` the lock from being opened by teeling.

In the accompanying drawings, I have shown one embodiment of the invention. In this showing:`

Figure 1 is a trent elevation,

Figure 2 is a central vertical sectional view, v

Figure 3 is a transverse vertical sectional view .on line 3 3 of Figure 2,

, Figure 4L is a horizontal sectional view on line 4--4 of Fignre 2,

Figure 5. is a detail sectional view on line 5 5 of Figure 2, y

i Figuren is a detail unassembled view of the rotating disks,

Figure 7 is a perspective view ot the hasp and pawl, and,

Figure `8 is a perspective view ot a spring washer arranged on top of the disks.

Referring to the drawings, the reference numeral 1 designates generally the casing ot `the lock which is formed in two sections to secure them to each other in any suitable Mmanner. `A top plate 2 is carried by one section ot the casing. Thisplate is pro`- 50 vided with openings adjacent each side for the passage of a shackle 3. One arm of the shackle terminates immediately within the casing andthe other arm is extended downwardly, indicated at 11V. The other section ot the casing is provided with a plate 5, adapted to be arranged beneath the top plate and limit the inward movement of the shackle.

A pin 6 is secured to the inside of the casing and extends transversely thereof. This pin is adapted to receive the rotating` disks by means ot which the locking pawl controlled.

The operating mechanism consists ot a lower disk 7 arranged on the pin 6, and provided with a ringgear 8 at its periphery. This disk is provided with a plurality of concentric openings 9,l arranged adjacent the center. These openings are threaded tor the reception otl a screw 10. A disk l1 is arranged over the bottom disk or gear 7, and this disk is provided with a plurality otopenings 12 concentrically arranged ad jacent the center, one of which is adapted to receive the screw 10. The openings 12 are spaced from each other a greater distance: than the openings 9. The disk 11 is provided with a notch 13 in its periphery and is turther provided with' a plurality ot notches 141, smaller in size than the notch 13. An upstanding pin 15 is mounted on the upper tace ofi' the disk. A. plurality ot disks 16 are arranged over thc disk 11 and these disks are provided with arcuate slots 17 'for the reception ot' the pin 15. shown, the slots vary in size, the slot in the lower disk being` smaller than the slot in the next adjacent disk, and the slot in the top disk being longer. rlhe disks are separated from each other by means ot washers 18 which washers are provided with arms 19 having openings 2O therein. These openings are adapted to` receive pins 21 carried by the casing, which prevent rotation of the washers and thus prevent rotation ot the disks by friction. Each ot the disks 16 is provided with a notch 22 `adapted to be alined with the notch 13 in the bottom disk when the lock is to be opened.

The disks are revolved by means of a knob or handle 2.3 arranged on the bottom of the lock casing and extending through the casing. The inner end ot this member is supported in a plate 24 and is provided with a pinion 2 5 meshing with the ring gear 8.

As s

The arm l oit the shackle is provided with a recess 26. A pawl 2i' is pivotally mounted on a pin 2S within the casing and the upper end ot this pawi provided with a tooth 25) arranged adjacent the disks and adapted torbe received in the notch 13 and rfhe opposite side of the paw] is provided with a tooth lit) adapted to be received in the recess 26 ot the shackle. The loweil end ot the pawl is provided with a toe 31 adapted to'be received in a groove 32 o'tl the rotatable operating men'iber. lt is further provided with a heel 3B arranged beneath the shackle and adapted to raise the shackle to the dotted line posit-ion shown in Figure 2 of the drawings, when the lock released and the pawl swung on its pivot.

The under tace o't the disk or gear T is provided with suitable indicia Sil andthe casing is provided with an opening' 35 through which the indicia ma7 be read. The easing is shaped to torni a pointer 3G to permit accnracv in readingthe iigures D K),.

The upper washer 18 is provided with a resilient arm 37 extending over the bod;7 ot the washer and having a central opening` tor the reception of the pin (i. rlhis arm engages the opposite side of the casing when in position (see Figure and forces the washers and disks into snug engagement with each other on the pin.

The operation ot the device is as tollows:

The gear 8 is revolved in iirst one direction and then the other by means ot the operating member. through the rotation ot the knob 23. When the gear is revolved, the bottom disk 1l moves with it and the pin 15, passing through the slot 1'?, will move each ot. the other disks 16 when the pin engages the end wall ot' the slot. The combination is read through the opening` and the operating member revolved in opposite directions the proper number ot times to arrange the notches 13 and 22 in alinenient with the tooth 29. then this has been accomplished. an outward pull on the knob 23 swings the pawl on its pivot to the dotted line position shown in Figure 2 ot the drawings, and the shackle is forced upwardly to lift the short arm ot the shackle over the top ot the casing. It will be apparent that ii the disks are not properl;7 set with the notches in alinement. the edges ot'pthe disks prevent the pawl Yfrom being swung on its pivot and the tooth 3() in engagement with the recess 26 prevents the shackle trom being litter. The tooth 29 of the pawl is provided with an extension 39 that will enter the notches 14 of the lower diskr 11 it an attempt is made to move the pawl on its pivot before the disk is properlv set.y b v pulling the knob 23 outwardly and locking the parts fainst further moenent. This preventsl combination. 'trom being set or released 'i'eeling7 Vlination may be changed debj.' aiiering the position or' the gear disk il with respect to each other. he screw lO ma;v be removed from the in which it is arranged and placed rent openings in these two memliers. ln order to provide a wide range ot' conr binations, the openings i) and 12 are arranged at diiierent distances Ytrom each. other. The combination may also be changed substituting disks lo having slots l? ot different sizes.

1tis to be understood that the torni oi my invention herewith shown and scribed is to be taken as a preferred e:;an1- ple ot the same. and that various changes in the shape, sir/ie, and arrangement ot parts ma)v be resorted to without departing from the spirit of the invention or the scope oi" the snbjoined claims.

Having thus described my invention, l claim:

1. A padlock comprising a casing. a shackle mounted in said casing, a pivot ally mounted paw] norma-H57 engaging said shackle to retain it in locked position. a gear mounted in said casing, a pin carried bv said gear, a pluralityv of disks arranged concentricallv with said gear. said disks being provided with arcuate slots for the reception ot' said pin and being further provided with notches adapted to be alined with said pawl to permit said pawl to be swung on its pivot to release said shackle` and means ior rotating said gear.

2. A. padlock comprising` a casing. a shackle mounted in said casing', a pivotallv mounted pawl normallyv engaging said shackle to retain it in locked position, a gear mounted in said casing, a pin carried bv said gear. a plnralitv ot disks arranged eoncentrica-llv with said gear, said disks being provided with arcuate slots tor the reception ot said pin and being further provided with notches adapted to be alined with said pawl to permit said pawl to be swungl on its pivot to release said shackle. and an operating member extending through said casing and connected to said gear to permit rotation of said gear.

3. A padlock comprising a casing. a shackle inonnted'in said casing. a pivotallv mounted pawl normally engaging said shackle to retain it in locked position, and means tor normally preventing movement oi said pawl. said means comprising a pluralit)v ot' disks, each oit said disks being provided with a notch in its peripherv adapted to be alined with said pawl to permit said pawl to be swung` on its pivot to release said shackle` an operating memberextending throughsaid casing and cond ey llO
